This picture gave me the idea for this headcanon :3Iwa-chan actually is really good with hair.
Once Oikawa asked him to cut his hair a bit because it got too long and like the good boyfriend he is, he agreed.
Iwa-chan slipped with the razor without Oikawa knowing and he panicked inside but continued cutting his boyfriend's hair really short at the sides.Voilà, Oikawa with an undercut.
As he looked in the mirror, his jaw dropped to the floor and he didn't talked to Iwaizumi for nearly 2 days but he started liking his new haircut.
Happy End •᎑• XD
